If you need to duplicate more of the hardware the cost to mine more increase much more.
It's an incentive to have a gaming rig that works as a miner when not gaming.
Perhaps, SBC's w/ mPCIe arent that expensive and id wager if it were the only way to mine $hotCoin in bulk then product would be developed pretty quickly to try and take advantage of the new market. Whilst this is strictly hypothetical i doubt the RoI would be bad enough to save us from GPU shortages.
Oh yeah sorry. I know what you mean now.
I meant, I should be more explicit.
Not just a simple gimp.
First it gimps so single gpu and single cpu are required.
Then it should actually have a hybrid proof of work code that requires half of it to be processed by the gpu and the other half to be processed by the cpu. If this is possible without leaving room for workarounds I do not know.
Also, you would have to make it so a better GPU scales with a better higher clocked /core count/ ipc CPU. So it encourages a balanced build.
TLDR
The point of all this is to have Miner Needs=Gamer Needs.
As a joke I would call this the proof-of-communist
It might have very interesting implications such as datacenters not being viable, and because the value of a gaming rig increases, the opportunity cost to go for a gaming rig over consoles is also lessened, hence more pc gamers. <-2 months later some1 comes up with a console based coin.
But yeah...just some idea from me.
